This baddest baddie in the Flipside Pit of 100 Trials. He may fight like Fracktail, but he's 100 times stronger.

Tattle

That's Wracktail, the very menacing lord of the Flipside Pit of 100 Trials. Max HP is ??. Attack is 10. It can fly and swoop down with its big open mouth... I think this is a prototype of an improved Fracktail from the Yold Desert... The Ancients must have built it. But like Fracktail, its antenna is its weak spot...

To defeat Wracktail, the same tactics must be utilized as those used to defeat Fracktail. The player must wait for the boss to dive low along the ground, then jump on his back and use Thoreau to grab the Wrackles and throw them and Wracktail's antenna, which must be hit 30 times to defeat the dragon. The player can also use Luigi's super jump to continuously jump onto the antenna, and Peach's parasol move can be used to easily jump back onto Wracktail's head when he does a loop, potentially making the battle easier than the earlier Fracktail battle. However, contrary to his Catch Card's claims, Wracktail is only ten times stronger than Fracktail, not 100 times.

He expresses anger at the heroes for disturbing his slumber and threatens to kill them in turn. After being beaten by them, he acknowledges that he was done, but then hints that he wasn't the only monster created by the Ancients, and that they go to the Flopside Pit of 100 Trials to find the other monster before being destroyed.

Possibly a pun on 「残」 zen, meaning "remain" (as Wracktail remains behind from the time of the Ancients), as well as ウンババ unbaba, the Japanese name of Blargg, which has been used in other previous Paper Mario series dragon names. Also resembles Fracktail's Japanese name, ズンババ Zunbaba.
